3.40.0 Release June 22, 2022

Docker Subdomain Connector PRO

Before this release, those with Docker repositories may have experienced scaling challenges related to the number of port connectors needed for their deployment. These customers had to set up a reverse proxy, and we know that this was often a pain point. In 3.34.0, we introduce a way to avoid using a reverse proxy: the subdomain connector for Docker.

By using a subdomain, you can reduce your deployment complexity, save on ongoing maintenance costs, and reduce administrative time and effort while improving Docker port scalability.

The problem is that each port connector consumes resources. The more port connectors you need, the more performance issues you are likely to encounter. In fact, if you need 20+ port connectors, you must set up a reverse proxy or subdomain to properly scale.

Best of all, setting up subdomain routing is easy. See theDocker subdomain connector documentationfor implementation information.

Note that SSL is required for Docker to work properly.

Maven Metadata Rebuild Optimizations for SQL Databases PRO

This release introduces a new SQL-based Maven metadata rebuild implementation to optimize rebuilding maven-metadata.xml files. This new implementation is enabled by default for SQL-based deployments.

If you must revert to the previous legacy SQL implementation Maven metadata rebuilder, you can do so by adding the following line to $data-dir/etc/nexus.properties:

nexus.maven.datastore.legacy.rebuild=true

Upgrade Database Migrator to Spring 5.3.18

While the Database Migrator is not vulnerable to CVE-2022-22965, out of an abundance of caution, we upgradedSpring Boot to 2.6.6, which upgrades Spring to 5.3.18.
